Binary Subtraction Operation

Function Name

$subtract(intA, intB)

Function Description

Implements the subtraction operation between parameter A and parameter B, which support the following types:

  • Numbers
  • Environment parameters
  • Local parameters
  • Binary operations

Application Scenarios

The binary subtraction function can be used in the following scenarios for API automation:

  • Request URL
  • Request header
  • Request body
  • Checkpoint property
  • if condition
  • for loop interrupt condition

Example

  • Request URL

    As shown in the following figure, the value of the test parameter in the request URL is the binary subtraction function. Parameters A and B in the function are 1001 and 1000 respectively.

  • Request header

    As shown in the following figure, the value of parameter subtract in the request header is the binary subtraction function. Parameter A in the function is the binary multiplication function $multiply(100,100), and parameter B is -1.

  • Request body

    As shown in the following figure, the binary subtraction function is used in the request body. Parameter A in the function is the binary division function $divide (1000,100), and parameter B is the binary addition function $add (1000,1000).

  • Checkpoint property

    As shown in the following figure, the target value of the checkpoint property result is the binary subtraction function. Parameter A in the function is the local parameter test, and parameter B is 1. For details about how to set local parameters, see Local Parameters.

  • if condition

    As shown in the following figure, the target value of the if condition is the binary subtraction function. Parameter A in the function is 1001, and parameter B is the environment variable status. For details about how to set environment parameters, see Setting Environment Parameters.

  • for loop interrupt condition

    As shown in the following figure, the target value of the for loop interrupt condition is the binary subtraction function. Parameters A and B in the function are 1001 and 1000 respectively.
